Shopify Speed Optimization

A fast Shopify store. Without ripping out your theme.

A focused speed engagement for small Shopify brands losing sales to slow load times. I audit, cut the bloat, fix Core Web Vitals, and ship the store you thought you were paying for — usually in 10–14 days.

What I fix

The full speed optimization checklist.

Nothing is "invisible" — I share the exact before/after report with you at the end. Every item below is in scope for the Full package.

App audit & cleanup

Identify heavy, duplicate, or unused apps. Remove, replace, or defer their scripts.

Image optimization

Proper dimensions, modern formats (WebP/AVIF), lazy-loading everything below the fold.

LCP element tuning

Preload the hero image, remove lazy-loading from the LCP, tighten render-blocking resources.

Theme & Liquid cleanup

Cut unused theme code, remove legacy sections, consolidate CSS, defer non-critical JS.

Third-party scripts

Audit GTM, chat, reviews, pixels — defer, async, or move server-side where possible.

Fonts & web fonts

Subset fonts, self-host where it helps, preload critical weights, remove unused variants.

CLS fixes

Reserve image dimensions, fix banner/announcement shifts, stabilize late-loading widgets.

INP / interactivity

Break up long tasks, reduce main-thread work, fix sluggish variant pickers and add-to-cart.

Caching & delivery

Validate CDN behavior, cache headers, and compression. Fix anything bypassing Shopify's edge.

Before/after report

Documented measurements — PageSpeed, CrUX, Lighthouse — across homepage, collection, product, cart.

Packages

How it works

Clear process, no surprises.

Free 20-minute call

We look at your store together, I pull an initial PageSpeed report, and we decide if I'm the right fit. No pitch, no pressure.

Fixed quote & scope

Within 24 hours you get a written scope, timeline, and fixed price. Nothing starts until you approve it.

Audit & baseline

I document every metric across homepage, collection, product, and cart — so we can prove the delta at the end.

Implement on staging

I duplicate your theme and work on a copy. Your live store stays untouched until you approve every change.

Launch + report

We publish when you're ready. You get a before/after report, a short walkthrough video, and 30 days of minor-fix support.

Fit check

Who this is for — and who it isn't.

✓ This is for you if…

  • You run a small/mid Shopify store doing under $3M/year.
  • You've verified your store is slow (PageSpeed below 50 on mobile).
  • You want a fixed scope with documented before/after results.
  • You can give me 2–3 hours of your time across the project.
  • You're open to removing apps that aren't earning their weight.

× This isn't for you if…

  • You want a full redesign — speed alone won't fix design problems.
  • You're on Shopify Plus with a custom headless setup (different scope).
  • You want "just change my hosting" — that's not how Shopify works.
  • You're not willing to remove any apps, no matter the cost.
  • You need 24/7 ongoing optimization (look at retainers instead).
FAQ

Questions before we work together.

Will this actually move PageSpeed score?
Yes — measurably. My typical Full Optimization result takes mobile PageSpeed from the 30–45 range into the 75–90 range, and all three Core Web Vitals into "Good". I'll show you previous before/after reports on the discovery call if you want proof.
What about my apps? I need them.
You're always in control. I'll tell you exactly what each app costs you in speed and revenue terms, and recommend which to remove, replace, or defer. You decide. Most stores I work on end up removing 2–4 apps they didn't realize were free-riding.
Do you work on my live theme?
Never. I duplicate your theme, work on the copy, and only publish when you've approved every change. Your live store is always safe.
What if speed drops again after you leave?
Within the first 30 days, any regression caused by my work is fixed free. After that, the report I leave you explains exactly what to watch for and what to avoid — so your next app install doesn't undo everything.
Can I just install a speed app instead?
Honestly? Usually no. Most speed apps either do very little or add their own bloat. They can't remove the real offenders: heavy themes, bad image workflows, render-blocking scripts, and misconfigured apps. If your problem is genuinely trivial, I'll tell you — and won't take the project.
Do you offer refunds?
Yes. If after the Focused Fix or Full Optimization you don't see a measurable PageSpeed improvement on the pages we agreed to target, I refund the implementation portion. That's almost never happened, but the guarantee is real.
